What happens to the value of the equilibrium constant (K) when a reaction is strongly endothermic and ∆ r H° is large and positive?

Options

  1. AK becomes much larger than 1
  2. BK becomes much smaller than 1
  3. CK remains unchanged
  4. DK is not affected by ∆ r H°

Correct answer

B. K becomes much smaller than 1

Step-by-step solution

When a reaction is strongly endothermic and ∆ r H° is large and positive, the value of K becomes much smaller than 1, indicating that the reaction is unlikely to form much product.
